Each cache entry is a +(guard_manager, out_code, next pointer). These are stored on the f_code's co_extra +scratch space. When a frame is invoked, we walk this linked list and run +guard_manager in each cache_entry to decide if the frame needs recompilation. If none +of the guard_manager's returns True, we recompile and add a new entry. To ensure we +don't end up recompiling infinitely, we put limits on the cache size. + +There are two limits +1) recompile_limit +2) accumulated_recompile_limit + + +Earlier we used to have only limit - maximum number of entries in 1 cache line +(which is now represented by (2) above). So, why do we need two limits? Lets try +to understand that. + +In general, we want our cache limit value to be a small number (e.g. 8 or even +lower). This ensures that for frames that cause too many recompilation fall to +eager quickly. However, there is another problem that prevents us from lowering +the value of recompile_limit. This is due to ID_MATCH'd guards. Today, we put +ID_MATCH guards on nn module if there is a graph break. This means we will have +many recompilations for the same code object because the ID_MATCH guard fails +for different instances of the nn module. This is a common pattern in how models +are authored. Therefore, this requires us to keep the recompile_limit high. + +We resolve this by introducing these two limits. The first limit (1) limits the +number of cache entries that have an ID_MATCH'd guard for an nn module instance. +And, (2)nd limit becomes a safeguard mechanism to have a maximum compilations +for a code object. One important question is - what is the limit for the code +object that does not have any ID_MATCH guard? For such code objects, we choose +(1) as the cache size limit. + +Lets take an example to understand how these limits help. Suppose, we have 16 +instances of a nn module and we ID_MATCH on the self object. Further, suppose +the inputs to these functions have varying batch size, leading to one +recompilation. In total, there will be 32 recompilations, and therefore 32 cache +entries on the forward code object. In the older case when we had only 1 limit, +our cache size limit must be >= 32 to capture all these recompilations. Now, +suppose there is a separate function in the same program which is very dynamic +and unsuitable for compilation.

With a job_id, at least you know there +# is some "state" associated with it. (State dict might be another way to +# tell if a run is related or not.) You can opt-in to YOLO everything +# aliases everything by passing a shared job_id for all your invocations. +# +# We choose to NOT share PGO cache across ranks. With no RANK_SHARING, there +# is never contention between runs, so we can leisurely update a bundle with +# information we need. Because we are grouped by job_id, we can have a single +# consolidated bundle for everything (or not; maybe worry about O(n^2) IO if +# we updated every compile--let's just instrument this.) Can even take a +# filelock for extra safety (expect no contention); expect 50ns overhead from +# uncontended filelock. +# +# If we did share ranks, everyone is storming to modify the same cache files. +# We can do this by having folks atomic write to a CAS-store and then having +# readers do on-the-fly merging (this can be implemented in remote using +# prefix iteration). As an optional optimization, one rank can be elected to +# handling bundling post facto (ideally, this is done async, after quiescence, +# without compiler collective need to wait for everyone to finish writing +# their bits.) Not sure how you can avoid a listdir because if some rank shows +# up with some new entries we need to pull them in ASAP (unless you want to +# delay bundling). +# +# But compiler collectives fill a similar niche: compilers chat with each +# other so rank 0 has collected everything. So elect rank 0 only to write the +# bundle. Don't even need CAS-store atomic write; just one rank writing an +# updating bundles.

Sharing a memory pool is an extremely +important optimization when chaining multiple CUDA graphs together, as it +prevents you from needing to copy intermediate tensors from one graph to the +next, and reduces overall memory usage by allowing dead memory from the first +pool to be reused in the second. + +The standard graph/make_graph_callables support sharing memory pool, but +with a lot of caveats.

In + other words: we support arbitrary trees of CUDA graph operations, not just + sequences (this is why this feature is called CUDA graph trees.) + +* Previously, if you executed graph A, some non-CUDA graph code, and then + graph B, after executing graph B, it was not safe to retain any references + to intermediates produced by A. With CUDA graph trees, we track if any +outputs of graph A are still live by the time graph B is run, and make + sure graph B doesn't clobber there memory when reusing the CUDA graphs + pool. You'll get a separate recording of B depending on what tensors + stay live or dead. + +CUDA graph trees are flexible enough to be used in Dynamo across graph breaks, +which is their primary use case. + +The ability to switch from replay to record is fairly nontrivial: remember that +when you replay a CUDA graph, you only replay CUDA operations; no CPU side state +is updated. In particular, the CPU-side book-keeping for the allocator is not +reconstructed. However, to record a new child CUDA graph, we must restore this +book-keeping.

Given a +search function and a replacement function this will register a replacement with +a pass (such as torch._inductor.fx_passes.joint_graph.patterns). + +Internally the pattern matcher represents patterns as a graph (a DAG). Creating +new patterns manually as a graph is cumbersome and error-prone so the standard +way to create patterns (using register_replacement()) is to provide a search +function and a replacement function which is traced and converted into a graph. + +Because the search functions are built somewhat generic (they tend to ignore +tensor sizes, for example) register_replacement() allows you to specify an +`extra_check` function which performs additional checks to verify that the +matched pattern fully matches before returning it. + +## Precompiled Patterns + +New patterns are added using register_replacement(). Patterns added in this way +can have a compile-time overhead because they need to be traced before +use. Patterns can be precompiled and added using gen_register_replacement() +instead. To do this you call gen_register_replacement() instead of +register_replacement().

Typically, +we will import V from this module:: + + from .virtualized import V + +Various handlers are accessible as attributes on this module; for example, +you might access ``V.graph.sizevars.size_hint`` to resolve a size hint associated with +a number. + +There are a few distinct usage patterns for virtualized global variables: + +1. Implicit argument passing. Examples: ``V.current_node``, ``V.aot_compilation``. + Use ``V.set_current_node`` to change what the current node is while we're + executing some region of code, so code inside that region can query ``V.current_node`` + to find out what it is. This is often more convenient than manually threading + the current node as an argument through all call stacks. + +2. Per-compilation global state. Examples: ``V.fake_mode``, ``V.graph``. For a + given ``compile_fx`` invocation, these typically don't change, but they are + associated with some internal state so they cannot just be global functions. + We install these objects at the beginning of compilation and then you can + conveniently access them without having to pass them around. + +3. Alternate define-by-run interpretations. Examples: ``V.ops``, ``V.kernel``. + A commonly used IR in Inductor is define-by-run: instead of maintaining + explicit syntax data structures, we instead represent loop bodies as + callable functions, which internally invoke operations defined on + ``V.ops``. To perform semantic analysis, print or code generate these + operations, we dynamically patch ``V.ops`` with an alternate handler with + the intended semantics and then run the callable function. For example, to + extract out a traditional (FX) graph representation of the define-by-run + IR, simply install a handler that records each ``ops`` call to a graph. + + TODO: Define a parent class / protocol that defines all of the operations + V.ops is expected to support. + +It is typically an error to access a virtualized global without having installed +an appropriate handler (you will get a NullHandler), although in some cases we +provide a default implementation. + +One last thing: although most virtualized globals are accessed via ``V``, ``ops`` is +ubiquitous enough to have its own top level variable, so you will typically see +``ops.constant(...)`` rather than ``V.ops.constant(...)``. In fact, these are not +equivalent; the former interface supports arithmetic overloads like ``x + y`` +instead of forcing ``ops.add(x, y)``, so it should be preferred. + +Some operators are seemingly unused, but they are implicitly used by ops_wrapper. +In particular, we typically have an operator for every basic pointwise PyTorch operation +supported. +""" + +from __future__ import annotations + +from contextlib import AbstractContextManager, contextmanager +from threading import local +from typing import Any, Callable, cast, Generic, TYPE_CHECKING, TypeVar, Union + +from torch.utils._ordered_set import OrderedSet + +from .ops_handler import ( # noqa: F401 + DefaultHandler, + KernelFormatterHandler, + MockHandler, + OpsHandler, + ReductionType, + StoreMode, + WrapperHandler, +) + + +if TYPE_CHECKING: + import torch + from torch._inductor.choices import InductorChoices + from torch._inductor.codegen.cpp_utils import LocalBufferContext + from torch._inductor.debug import DebugContext + from torch._inductor.graph import GraphLowering + from torch._inductor.ir import ExternKernelNode + from torch._inductor.loop_body import InterpreterShim + from torch._subclasses import FakeTensorMode + +threadlocal = local() + +T = TypeVar("T") + + +class NullHandler: + """ + Sentinel indicating that a global variable is unset ala None.

This package +generally follows the design of the `TensorFlow Distributions`_ package. + +.. _`TensorFlow Distributions`: + https://arxiv.org/abs/1711.10604 + +It is not possible to directly backpropagate through random samples.

Whilst the score function only requires the value +of samples :math:`f(x)`, the pathwise derivative requires the derivative +:math:`f'(x)`. The next sections discuss these two in a reinforcement learning +example.

Currently, due to implementation constraints (explained + below), SparseAdam is only intended for a narrow subset of use cases, specifically + parameters of a dense layout with gradients of a sparse layout. This occurs in a + special case where the module backwards produces grads already in a sparse layout. + One example NN module that behaves as such is ``nn.Embedding(sparse=True)``. + + SparseAdam approximates the Adam algorithm by masking out the parameter and moment + updates corresponding to the zero values in the gradients. Whereas the Adam algorithm + will update the first moment, the second moment, and the parameters based on all values + of the gradients, SparseAdam only updates the moments and parameters corresponding + to the non-zero values of the gradients. + + A simplified way of thinking about the `intended` implementation is as such: + + 1. Create a mask of the non-zero values in the sparse gradients. For example, + if your gradient looks like [0, 5, 0, 0, 9], the mask would be [0, 1, 0, 0, 1]. + 2. Apply this mask over the running moments and do computation on only the + non-zero values. + 3. Apply this mask over the parameters and only apply an update on non-zero values. + + In actuality, we use sparse layout Tensors to optimize this approximation, which means the + more gradients that are masked by not being materialized, the more performant the optimization. + Since we rely on using sparse layout tensors, we infer that any materialized value in the + sparse layout is non-zero and we do NOT actually verify that all values are not zero! + It is important to not conflate a semantically sparse tensor (a tensor where many + of its values are zeros) with a sparse layout tensor (a tensor where ``.is_sparse`` + returns ``True``). The SparseAdam approximation is intended for `semantically` sparse + tensors and the sparse layout is only a implementation detail. A clearer implementation + would be to use MaskedTensors, but those are experimental. + + + .. note:: + + If you suspect your gradients are semantically sparse (but do not have sparse + layout), this variant may not be the best for you. Ideally, you want to avoid + materializing anything that is suspected to be sparse in the first place, since + needing to convert all your grads from dense layout to sparse layout may outweigh + the performance gain. Here, using Adam may be the best alternative, unless you + can easily rig up your module to output sparse grads similar to + ``nn.Embedding(sparse=True)``. If you insist on converting your grads, you can do + so by manually overriding your parameters' ``.grad`` fields with their sparse + equivalents before calling ``.step()``. + + + Args: + {_params_doc} + lr (float, Tensor, optional): learning rate (default: 1e-3) + betas (Tuple[float, float], optional): coefficients used for computing + running averages of gradient and its square (default: (0.9, 0.999)) + eps (float, optional): term added to the denominator to improve + numerical stability (default: 1e-8) + {_maximize_doc} + + .. _Adam\: A Method for Stochastic Optimization: + https://arxiv.org/abs/1412.6980 + + """ diff --git a/Scripts_Climate_n_LAI_to_Yield/.venv/lib/python3.10/site-packages/torch/optim/swa_utils.py b/Scripts_Climate_n_LAI_to_Yield/.venv/lib/python3.10/site-packages/torch/optim/swa_utils.py new file mode 100644 index 0000000000000000000000000000000000000000..da4f005820c6824b595b3c8316b95b9cef93b1f9 --- /dev/null +++ b/Scripts_Climate_n_LAI_to_Yield/.venv/lib/python3.10/site-packages/torch/optim/swa_utils.py @@ -0,0 +1,484 @@ +# mypy: allow-untyped-defs +r"""Implementation for Stochastic Weight Averaging implementation.""" + +import itertools +import math +import warnings +from collections.abc import Iterable +from copy import deepcopy +from typing import Any, Callable, cast, Literal, Optional, Union + +import torch +from torch import Tensor +from torch.nn import Module +from torch.optim.lr_scheduler import _format_param, LRScheduler +from torch.utils._foreach_utils import _get_foreach_kernels_supported_devices + +from .optimizer import Optimizer + + +__all__ = [ + "AveragedModel", + "update_bn", + "SWALR", + "get_ema_multi_avg_fn", + "get_swa_multi_avg_fn", + "get_ema_avg_fn", + "get_swa_avg_fn", +] + +from torch.utils._foreach_utils import _group_tensors_by_device_and_dtype + + +PARAM_LIST = Union[tuple[Tensor, ...], list[Tensor]] + + +def get_ema_multi_avg_fn(decay=0.999): + """Get the function applying exponential moving average (EMA) across multiple params.""" + + if decay < 0.0 or decay > 1.0: + raise ValueError( + f"Invalid decay value {decay} provided.

This +module does not search for the NVIDIA CUDA Samples. + +.. versionadded:: 3.19 + QNX support. + +Search Behavior +^^^^^^^^^^^^^^^ + +The CUDA Toolkit search behavior uses the following order: + +1. If the ``CUDA`` language has been enabled we will use the directory + containing the compiler as the first search location for ``nvcc``. + +2. If the ``CUDAToolkit_ROOT`` cmake configuration variable (e.g., + ``-DCUDAToolkit_ROOT=/some/path``) *or* environment variable is defined, it + will be searched. If both an environment variable **and** a + configuration variable are specified, the *configuration* variable takes + precedence. + + The directory specified here must be such that the executable ``nvcc`` or + the appropriate ``version.txt`` file can be found underneath the specified + directory. + +3. If the CUDA_PATH environment variable is defined, it will be searched + for ``nvcc``. + +4. The user's path is searched for ``nvcc`` using :command:`find_program`. If + this is found, no subsequent search attempts are performed. Users are + responsible for ensuring that the first ``nvcc`` to show up in the path is + the desired path in the event that multiple CUDA Toolkits are installed. + +5. On Unix systems, if the symbolic link ``/usr/local/cuda`` exists, this is + used. No subsequent search attempts are performed. No default symbolic link + location exists for the Windows platform. + +6. The platform specific default install locations are searched. If exactly one + candidate is found, this is used. The default CUDA Toolkit install locations + searched are: + + +-------------+-------------------------------------------------------------+ + | Platform | Search Pattern | + +=============+=============================================================+ + | macOS | ``/Developer/NVIDIA/CUDA-X.Y`` | + +-------------+-------------------------------------------------------------+ + | Other Unix | ``/usr/local/cuda-X.Y`` | + +-------------+-------------------------------------------------------------+ + | Windows | ``C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\vX.Y`` | + +-------------+-------------------------------------------------------------+ + + Where ``X.Y`` would be a specific version of the CUDA Toolkit, such as + ``/usr/local/cuda-9.0`` or + ``C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0`` + + .. note:: + + When multiple CUDA Toolkits are installed in the default location of a + system(e.g., both ``/usr/local/cuda-9.0`` and ``/usr/local/cuda-10.0`` + exist but the ``/usr/local/cuda`` symbolic link does **not** exist), this + package is marked as **not** found. + + There are too many factors involved in making an automatic decision in + the presence of multiple CUDA Toolkits being installed. In this + situation, users are encouraged to either (1) set ``CUDAToolkit_ROOT`` or + (2) ensure that the correct ``nvcc`` executable shows up in ``$PATH`` for + :command:`find_program` to find. + +Arguments +^^^^^^^^^ + +``[]`` + The ``[]`` argument requests a version with which the package found + should be compatible. See :ref:`find_package version format ` + for more details. + +Options +^^^^^^^ + +``REQUIRED`` + If specified, configuration will error if a suitable CUDA Toolkit is not + found. + +``QUIET`` + If specified, the search for a suitable CUDA Toolkit will not produce any + messages. + +``EXACT`` + If specified, the CUDA Toolkit is considered found only if the exact + ``VERSION`` specified is recovered. + +Imported targets +^^^^^^^^^^^^^^^^ + +An :ref:`imported target ` named ``CUDA::toolkit`` is provided. + +This module defines :prop_tgt:`IMPORTED` targets for each +of the following libraries that are part of the CUDAToolkit: + +- :ref:`CUDA Runtime Library` +- :ref:`CUDA Driver Library` +- :ref:`cuBLAS` +- :ref:`cuFFT` +- :ref:`cuRAND` +- :ref:`cuSOLVER` +- :ref:`cuSPARSE` +- :ref:`cuPTI` +- :ref:`NPP` +- :ref:`nvBLAS` +- :ref:`nvGRAPH` +- :ref:`nvJPEG` +- :ref:`nvidia-ML` +- :ref:`nvRTC` +- :ref:`nvToolsExt` +- :ref:`OpenCL` +- :ref:`cuLIBOS` + +.. _`cuda_toolkit_rt_lib`: + +CUDA Runtime Library +"""""""""""""""""""" + +The CUDA Runtime library (cudart) are what most applications will typically +need to link against to make any calls such as `cudaMalloc`, and `cudaFree`. + +Targets Created: + +- ``CUDA::cudart`` +- ``CUDA::cudart_static`` + +.. _`cuda_toolkit_driver_lib`: + +CUDA Driver Library +"""""""""""""""""""" + +The CUDA Driver library (cuda) are used by applications that use calls +such as `cuMemAlloc`, and `cuMemFree`. + +Targets Created: + +- ``CUDA::cuda_driver`` + +.. _`cuda_toolkit_cuBLAS`: + +cuBLAS +"""""" + +The `cuBLAS `_ library. + +Targets Created: + +- ``CUDA::cublas`` +- ``CUDA::cublas_static`` +- ``CUDA::cublasLt`` starting in CUDA 10.1 +- ``CUDA::cublasLt_static`` starting in CUDA 10.1 + +.. _`cuda_toolkit_cuFFT`: + +cuFFT +""""" + +The `cuFFT `_ library. + +Targets Created: + +- ``CUDA::cufft`` +- ``CUDA::cufftw`` +- ``CUDA::cufft_static`` +- ``CUDA::cufft_static_nocallback`` starting in CUDA 9.2, requires CMake 3.23+ +- ``CUDA::cufftw_static`` + +cuRAND +"""""" + +The `cuRAND `_ library. + +Targets Created: + +- ``CUDA::curand`` +- ``CUDA::curand_static`` + +.. _`cuda_toolkit_cuSOLVER`: + +cuSOLVER +"""""""" + +The `cuSOLVER `_ library. + +Targets Created: + +- ``CUDA::cusolver`` +- ``CUDA::cusolver_static`` + +.. _`cuda_toolkit_cuSPARSE`: + +cuSPARSE +"""""""" + +The `cuSPARSE `_ library. + +Targets Created: + +- ``CUDA::cusparse`` +- ``CUDA::cusparse_static`` + +.. _`cuda_toolkit_cupti`: + +cupti +""""" + +The `NVIDIA CUDA Profiling Tools Interface `_. + +Targets Created: + +- ``CUDA::cupti`` +- ``CUDA::cupti_static`` + +.. _`cuda_toolkit_NPP`: + +NPP +""" + +The `NPP `_ libraries. + +Targets Created: + +- `nppc`: + + -

Note that +# this is a function and not a macro. +# +# CUDA_INCLUDE_DIRECTORIES( path0 path1 ... ) +# -- Sets the directories that should be passed to nvcc +# (e.g. nvcc -Ipath0 -Ipath1 ... ). These paths usually contain other .cu +# files. +# +# +# CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS( output_file_var cuda_target +# nvcc_flags object_files) +# -- Generates the link object required by separable compilation from the given +# object files. This is called automatically for CUDA_ADD_EXECUTABLE and +# CUDA_ADD_LIBRARY, but can be called manually when using CUDA_WRAP_SRCS +# directly. When called from CUDA_ADD_LIBRARY or CUDA_ADD_EXECUTABLE the +# nvcc_flags passed in are the same as the flags passed in via the OPTIONS +# argument. The only nvcc flag added automatically is the bitness flag as +# specified by CUDA_64_BIT_DEVICE_CODE. Note that this is a function +# instead of a macro. +# +# CUDA_SELECT_NVCC_ARCH_FLAGS(out_variable [target_CUDA_architectures]) +# -- Selects GPU arch flags for nvcc based on target_CUDA_architectures +# target_CUDA_architectures : Auto | Common | All | LIST(ARCH_AND_PTX ...) +# - "Auto" detects local machine GPU compute arch at runtime. +# - "Common" and "All" cover common and entire subsets of architectures +# ARCH_AND_PTX : NAME | NUM.NUM | NUM.NUM(NUM.NUM) | NUM.NUM+PTX +# NAME: Kepler Maxwell Kepler+Tesla Maxwell+Tegra Pascal Volta Turing +# NUM: Any number. Only those pairs are currently accepted by NVCC though: +# 3.5 3.7 5.0 5.2 5.3 6.0 6.1 6.2 7.0 7.2 7.5 +# Returns LIST of flags to be added to CUDA_NVCC_FLAGS in ${out_variable} +# Additionally, sets ${out_variable}_readable to the resulting numeric list +# Example: +# CUDA_SELECT_NVCC_ARCH_FLAGS(ARCH_FLAGS 3.0 3.5+PTX 5.2(5.0) Maxwell) +# LIST(APPEND CUDA_NVCC_FLAGS ${ARCH_FLAGS}) +# +# More info on CUDA architectures: https://en.wikipedia.org/wiki/CUDA +# Note that this is a function instead of a macro. +# +# CUDA_WRAP_SRCS ( cuda_target format generated_files file0 file1 ... +# [STATIC | SHARED | MODULE] [OPTIONS ...] ) +# -- This is where all the magic happens. CUDA_ADD_EXECUTABLE, +# CUDA_ADD_LIBRARY, CUDA_COMPILE, and CUDA_COMPILE_PTX all call this +# function under the hood. +# +# Given the list of files (file0 file1 ... fileN) this macro generates +# custom commands that generate either PTX or linkable objects (use "PTX" or +# "OBJ" for the format argument to switch). Files that don't end with .cu +# or have the HEADER_FILE_ONLY property are ignored. +# +# The arguments passed in after OPTIONS are extra command line options to +# give to nvcc. You can also specify per configuration options by +# specifying the name of the configuration followed by the options. General +# options must precede configuration specific options. Not all +# configurations need to be specified, only the ones provided will be used. +# +# OPTIONS -DFLAG=2 "-DFLAG_OTHER=space in flag" +# DEBUG -g +# RELEASE --use_fast_math +# RELWITHDEBINFO --use_fast_math;-g +# MINSIZEREL --use_fast_math +# +# For certain configurations (namely VS generating object files with +# CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE set to ON), no generated file will +# be produced for the given cuda file. This is because when you add the +# cuda file to Visual Studio it knows that this file produces an object file +# and will link in the resulting object file automatically. +# +# This script will also generate a separate cmake script that is used at +# build time to invoke nvcc. This is for several reasons. +# +# 1. nvcc can return negative numbers as return values which confuses +# Visual Studio into thinking that the command succeeded. The script now +# checks the error codes and produces errors when there was a problem. +# +# 2. nvcc has been known to not delete incomplete results when it +# encounters problems. This confuses build systems into thinking the +# target was generated when in fact an unusable file exists. The script +# now deletes the output files if there was an error. +# +# 3. By putting all the options that affect the build into a file and then +# make the build rule dependent on the file, the output files will be +# regenerated when the options change. +# +# This script also looks at optional arguments STATIC, SHARED, or MODULE to +# determine when to target the object compilation for a shared library. +# BUILD_SHARED_LIBS is ignored in CUDA_WRAP_SRCS, but it is respected in +# CUDA_ADD_LIBRARY. On some systems special flags are added for building +# objects intended for shared libraries. A preprocessor macro, +# _EXPORTS is defined when a shared library compilation is +# detected. +# +# Flags passed into add_definitions with -D or /D are passed along to nvcc. +# +# +# +# The script defines the following variables:: +# +# CUDA_VERSION_MAJOR -- The major version of cuda as reported by nvcc. +# CUDA_VERSION_MINOR -- The minor version. +# CUDA_VERSION +# CUDA_VERSION_STRING -- CUDA_VERSION_MAJOR.CUDA_VERSION_MINOR +# CUDA_HAS_FP16 -- Whether a short float (float16,fp16) is supported. +# +# CUDA_TOOLKIT_ROOT_DIR -- Path to the CUDA Toolkit (defined if not set). +# CUDA_SDK_ROOT_DIR -- Path to the CUDA SDK. Use this to find files in the +# SDK. This script will not directly support finding +# specific libraries or headers, as that isn't +# supported by NVIDIA. If you want to change +# libraries when the path changes see the +# FindCUDA.cmake script for an example of how to clear +# these variables. There are also examples of how to +# use the CUDA_SDK_ROOT_DIR to locate headers or +# libraries, if you so choose (at your own risk). +# CUDA_INCLUDE_DIRS -- Include directory for cuda headers.

It is + expected that all measurements should include replicates to quantify + noise and allow median computation, which is more robust than mean. + To that effect, this class deviates from the `timeit` API by + conceptually merging `timeit.Timer.repeat` and `timeit.Timer.autorange`. + (Exact algorithms are discussed in method docstrings.) The `timeit` + method is replicated for cases where an adaptive strategy is not + desired. + + 3) Optional metadata: + When defining a Timer, one can optionally specify `label`, `sub_label`, + `description`, and `env`. (Defined later) These fields are included in + the representation of result object and by the `Compare` class to group + and display results for comparison. + + 4) Instruction counts + In addition to wall times, Timer can run a statement under Callgrind + and report instructions executed. + + Directly analogous to `timeit.Timer` constructor arguments: + + `stmt`, `setup`, `timer`, `globals` + + PyTorch Timer specific constructor arguments: + + `label`, `sub_label`, `description`, `env`, `num_threads` + + Args: + stmt: Code snippet to be run in a loop and timed. + + setup: Optional setup code.

If gcc believes + the CFA is in %rsp, then unwinding may fail, because what's at the + CFA is not what gcc "expected" when it constructs the CFIs for the + places where the macros are instantiated. + + But we can't just add a CFI annotation to increase the CFA offset + by 128, to match the sub of 128 from %rsp, because we don't know + whether gcc has chosen %rsp as the CFA at that point, or whether it + has chosen some other register (eg, %rbp). In the latter case, + adding a CFI annotation to change the CFA offset is simply wrong. + + So the solution is to get hold of the CFA using + __builtin_dwarf_cfa(), put it in a known register, and add a + CFI annotation to say what the register is. We choose %rbp for + this (perhaps perversely), because: + + (1) %rbp is already subject to unwinding. If a new register was + chosen then the unwinder would have to unwind it in all stack + traces, which is expensive, and + + (2) %rbp is already subject to precise exception updates in the + JIT. If a new register was chosen, we'd have to have precise + exceptions for it too, which reduces performance of the + generated code. + + However .. one extra complication. We can't just whack the result + of __builtin_dwarf_cfa() into %rbp and then add %rbp to the + list of trashed registers at the end of the inline assembly + fragments; gcc won't allow %rbp to appear in that list. Hence + instead we need to stash %rbp in %r15 for the duration of the asm, + and say that %r15 is trashed instead. gcc seems happy to go with + that. + + Oh .. and this all needs to be conditionalised so that it is + unchanged from before this commit, when compiled with older gccs + that don't support __builtin_dwarf_cfa. Furthermore, since + this header file is freestanding, it has to be independent of + config.h, and so the following conditionalisation cannot depend on + configure time checks. + + Although it's not clear from + 'defined(__GNUC__) && defined(__GCC_HAVE_DWARF2_CFI_ASM)', + this expression excludes Darwin. + .cfi directives in Darwin assembly appear to be completely + different and I haven't investigated how they work. + + For even more entertainment value, note we have to use the + completely undocumented __builtin_dwarf_cfa(), which appears to + really compute the CFA, whereas __builtin_frame_address(0) claims + to but actually doesn't.

This + happens automatically for the standard allocator functions such as + malloc(), calloc(), realloc(), memalign(), new, new[], free(), delete, + delete[], etc. + + But if your program uses a custom allocator, this doesn't automatically + happen, and Valgrind will not do as well. For example, if you allocate + superblocks with mmap() and then allocates chunks of the superblocks, all + Valgrind's observations will be at the mmap() level and it won't know that + the chunks should be considered separate entities. In Memcheck's case, + that means you probably won't get heap block overrun detection (because + there won't be redzones marked as unaddressable) and you definitely won't + get any leak detection. + + The following client requests allow a custom allocator to be annotated so + that it can be handled accurately by Valgrind. + + VALGRIND_MALLOCLIKE_BLOCK marks a region of memory as having been allocated + by a malloc()-like function. For Memcheck (an illustrative case), this + does two things: + + - It records that the block has been allocated. This means any addresses + within the block mentioned in error messages will be + identified as belonging to the block. It also means that if the block + isn't freed it will be detected by the leak checker. + + - It marks the block as being addressable and undefined (if 'is_zeroed' is + not set), or addressable and defined (if 'is_zeroed' is set). This + controls how accesses to the block by the program are handled. + + 'addr' is the start of the usable block (ie. after any + redzone), 'sizeB' is its size. 'rzB' is the redzone size if the allocator + can apply redzones -- these are blocks of padding at the start and end of + each block. Adding redzones is recommended as it makes it much more likely + Valgrind will spot block overruns. `is_zeroed' indicates if the memory is + zeroed (or filled with another predictable value), as is the case for + calloc(). + + VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a + heap block -- that will be used by the client program -- is allocated. + It's best to put it at the outermost level of the allocator if possible; + for example, if you have a function my_alloc() which calls + internal_alloc(), and the client request is put inside internal_alloc(), + stack traces relating to the heap block will contain entries for both + my_alloc() and internal_alloc(), which is probably not what you want. + + For Memcheck users: if you use VALGRIND_MALLOCLIKE_BLOCK to carve out + custom blocks from within a heap block, B, that has been allocated with + malloc/calloc/new/etc, then block B will be *ignored* during leak-checking + -- the custom blocks will take precedence. + + VALGRIND_FREELIKE_BLOCK is the partner to VALGRIND_MALLOCLIKE_BLOCK. For + Memcheck, it does two things: + + - It records that the block has been deallocated. This assumes that the + block was annotated as having been allocated via + VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued. + + - It marks the block as being unaddressable. + + VALGRIND_FREELIKE_BLOCK should be put immediately after the point where a + heap block is deallocated. + + VALGRIND_RESIZEINPLACE_BLOCK informs a tool about reallocation. For + Memcheck, it does four things: + + - It records that the size of a block has been changed. This assumes that + the block was annotated as having been allocated via + VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued. + + - If the block shrunk, it marks the freed memory as being unaddressable. + + - If the block grew, it marks the new area as undefined and defines a red + zone past the end of the new block. + + - The V-bits of the overlap between the old and the new block are preserved. + + VALGRIND_RESIZEINPLACE_BLOCK should be put after allocation of the new block + and before deallocation of the old block. + + In many cases, these three client requests will not be enough to get your + allocator working well with Memcheck. More specifically, if your allocator + writes to freed blocks in any way then a VALGRIND_MAKE_MEM_UNDEFINED call + will be necessary to mark the memory as addressable just before the zeroing + occurs, otherwise you'll get a lot of invalid write errors. For example, + you'll need to do this if your allocator recycles freed blocks, but it + zeroes them before handing them back out (via VALGRIND_MALLOCLIKE_BLOCK). + Alternatively, if your allocator reuses freed blocks for allocator-internal + data structures, VALGRIND_MAKE_MEM_UNDEFINED calls will also be necessary. + + Really, what's happening is a blurring of the lines between the client + program and the allocator... after VALGRIND_FREELIKE_BLOCK is called, the + memory should be considered unaddressable to the client program, but the + allocator knows more than the rest of the client program and so may be able + to safely access it.

The inputs of inner checkpoints are treated as tensors saved to its +# parent checkpoint. +# +# Implication: To recompute any given saved tensor, we need to recompute all of +# the checkpoints wrapping it. +# +# Why is this implied? To unpack a saved tensor X during backward we need to +# recompute the inner-most checkpoint (#1), and in order to recompute that +# checkpoint I need to have its inputs, which are managed by that checkpoint's +# parent (#2), which thus also needs to be recomputed first. Continue this line +# of reasoning and we realize that in order to unpack X, all checkpoints that +# were active at the time X was saved need to be recomputed. (unless we have +# already done so in that backward for some other saved tensor). +# +# In practice, we use a noop autograd Function to save inputs as saved tensors. +# During unpack calling ctx.saved_tensor triggers the parent checkpoint to +# recompute. +# +# Rule 3. We should start recomputation as if there are no checkpoints currently +# active. Checkpoints encountered during recomputation are still +# respected. +# +# When we start recomputation, we push the saved variable hook meant for +# recomputation on the stack. See examples in Rule 6 for more context. +# +# * * * * +# +# Beyond the basic semantics specific to nested checkpoint, we impose several +# more constraints that may apply to checkpointing in general. +# +# Rule 4.

Instead of packing the strong reference to the key +# directly, we pack a container object, which we manually clear as we unpack. +# +# An important detail is that if a second backward happens, the second +# recomputation needs to reset the container with a newly created key. +# +# Rule 5.

If a visible card has a compute capability (CC) that's + newer than the newest version for which your nvcc can build fully-compiled binaries, PyTorch + will make nvcc fall back to building kernels with the newest version of PTX your nvcc does + support (see below for details on PTX). + + You can override the default behavior using `TORCH_CUDA_ARCH_LIST` to explicitly specify which + CCs you want the extension to support: + + ``TORCH_CUDA_ARCH_LIST="6.1 8.6" python build_my_extension.py`` + ``TORCH_CUDA_ARCH_LIST="5.2 6.0 6.1 7.0 7.5 8.0 8.6+PTX" python build_my_extension.py`` + + The +PTX option causes extension kernel binaries to include PTX instructions for the specified + CC. PTX is an intermediate representation that allows kernels to runtime-compile for any CC >= + the specified CC (for example, 8.6+PTX generates PTX that can runtime-compile for any GPU with + CC >= 8.6). This improves your binary's forward compatibility. However, relying on older PTX to + provide forward compat by runtime-compiling for newer CCs can modestly reduce performance on + those newer CCs.

So a message will also +be printed from the worker process when it is killed by such signals. + +See NOTE [ Data Loader Multiprocessing Shutdown Logic ] for the reasoning of +this signal handling design and other mechanism we implement to make our +multiprocessing data loading robust to errors. +""" + +import signal +import threading + +# Some of the following imported functions are not used in this file, but are to +# be used `_utils.signal_handling.XXXXX`. +from torch._C import ( # noqa: F401 + _error_if_any_worker_fails, + _remove_worker_pids, + _set_worker_pids, + _set_worker_signal_handlers, +) + +from . import IS_WINDOWS + + +_SIGCHLD_handler_set = False +r"""Whether SIGCHLD handler is set for DataLoader worker failures.

Even if it is called, by the time it executes, + # many Python core library resources may already be freed, and even + # simple things like acquiring an internal lock of a queue may hang. + # Therefore, in this case, we actually need to prevent `__del__` from + # being executed, and rely on the automatic termination of daemonic + # children. + # + # Thus, we register an `atexit` hook that sets a global flag + # `_utils.python_exit_status`. Since `atexit` hooks are executed in the + # reverse order of registration, we are guaranteed that this flag is + # set before library resources we use are freed (which, at least in + # CPython, is done via an `atexit` handler defined in + # `multiprocessing/util.py` + # https://github.com/python/cpython/blob/c606624af8d4cb3b4a052fb263bb983b3f87585b/Lib/multiprocessing/util.py#L320-L362 + # registered when an object requiring this mechanism is first + # created, e.g., `mp.Queue` + # https://github.com/python/cpython/blob/c606624af8d4cb3b4a052fb263bb983b3f87585b/Lib/multiprocessing/context.py#L100-L103 + # https://github.com/python/cpython/blob/c606624af8d4cb3b4a052fb263bb983b3f87585b/Lib/multiprocessing/queues.py#L29 + # ) + # + # So in `__del__`, we check if `_utils.python_exit_status` is set or + # `None` (freed), and perform no-op if so. + # + # However, simply letting library clean-up codes run can also be bad, + # because such codes (i.e., `multiprocessing.util._exit_function()`) + # include join putting threads for `mp.Queue`, which can be blocking. + # Hence, the main process putting threads are called with + # `cancel_join_thread` at creation. See later section + # [ 3b. A process won't hang when putting into a queue; ] + # for more details. + # + # Here are two example cases where library clean-up codes can run + # before `__del__` is called: + # + # 1. If we hold onto a reference to the iterator, it more often + # than not tries to do `multiprocessing` library cleaning before + # clearing the alive referenced objects (https://github.com/pytorch/pytorch/issues/48666) + # and thus prevents our cleaning-up code to run first. + # + # 2. A similar issue araises when a `DataLoader` is used in a subprocess. + # When a process ends, it shuts the all its daemonic children + # down with a SIGTERM (instead of joining them without a timeout). + # Similarly for threads, but by a different mechanism. This fact, + # together with a few implementation details of multiprocessing, forces + # us to make workers daemonic. All of our problems arise when a + # DataLoader is used in a subprocess, and are caused by multiprocessing + # code which looks more or less like this: + # + # try: + # your_function_using_a_dataloader() + # finally: + # multiprocessing.util._exit_function() + # + # The joining/termination mentioned above happens inside + # `_exit_function()`. Now, if `your_function_using_a_dataloader()` + # throws, the stack trace stored in the exception will prevent the + # frame which uses `DataLoaderIter` to be freed. If the frame has any + # reference to the `DataLoaderIter` (e.g., in a method of the iter), + # its `__del__`, which starts the shutdown procedure, will not be + # called. That, in turn, means that workers aren't notified. Attempting + # to join in `_exit_function` will then result in a hang. + # + # For context, `_exit_function` is also registered as an `atexit` call. + # So it is unclear to me (@ssnl) why this is needed in a finally block. + # The code dates back to 2008 and there is no comment on the original + # PEP 371 or patch https://bugs.python.org/issue3050 (containing both + # the finally block and the `atexit` registration) that explains this. + # + # + # Finally, another choice is to just shutdown workers with logic in 1 + # above whenever we see an error in `next`. This isn't ideal because + # a. It prevents users from using try-catch to resume data loading. + # b. It doesn't prevent hanging if users have references to the + # iterator. + # + # 3. All processes exit if any of them die unexpectedly by fatal signals. + # + # As shown above, the workers are set as daemonic children of the main + # process. However, automatic cleaning-up of such child processes only + # happens if the parent process exits gracefully (e.g., not via fatal + # signals like SIGKILL). So we must ensure that each process will exit + # even the process that should send/receive data to/from it were + # killed, i.e., + # + # a. A process won't hang when getting from a queue. + # + # Even with carefully designed data dependencies (i.e., a `put()` + # always corresponding to a `get()`), hanging on `get()` can still + # happen when data in queue is corrupted (e.g., due to + # `cancel_join_thread` or unexpected exit). + # + # For child exit, we set a timeout whenever we try to get data + # from `data_queue`, and check the workers' status on each timeout + # and error. + # See `_DataLoaderiter._get_batch()` and + # `_DataLoaderiter._try_get_data()` for details. + # + # Additionally, for child exit on non-Windows platforms, we also + # register a SIGCHLD handler (which is supported on Windows) on + # the main process, which checks if any of the workers fail in the + # (Python) handler. This is more efficient and faster in detecting + # worker failures, compared to only using the above mechanism. + # See `DataLoader.cpp` and `_utils/signal_handling.py` for details. + # + # For `.get()` calls where the sender(s) is not the workers, we + # guard them with timeouts, and check the status of the sender + # when timeout happens: + # + in the workers, the `_utils.worker.ManagerWatchdog` class + # checks the status of the main process. + # + if `pin_memory=True`, when getting from `pin_memory_thread`, + # check `pin_memory_thread` status periodically until `.get()` + # returns or see that `pin_memory_thread` died. + # + # b. A process won't hang when putting into a queue; + # + # We use `mp.Queue` which has a separate background thread to put + # objects from an unbounded buffer array. The background thread is + # daemonic and usually automatically joined when the process + # *exits*. + # + # In case that the receiver has ended abruptly while + # reading from the pipe, the join will hang forever. The usual + # solution for this in Python is calling `q.cancel_join_thread`, + # which prevents automatically joining it when finalizing + # (exiting). + # + # Nonetheless, `cancel_join_thread` must only be called when the + # queue is **not** going to be read from or write into by another + # process, because it may hold onto a lock or leave corrupted data + # in the queue, leading other readers/writers to hang. + # + # Hence, + # + For worker processes, we only do so (for their output + # queues, i.e., `worker_result_queue`) before exiting. + # + For `pin_memory_thread`, its output queue `data_queue` is a + # `queue.Queue` that does blocking `put` if the queue is full. + # So there is no above problem, but as a result, in + # `_pin_memory_loop`, we do need to wrap the `put` in a loop + # that breaks not only upon success, but also when the main + # process stops reading, i.e., is shutting down. + # + For loader process, we `cancel_join_thread()` for all + # `_index_queues` because the whole purpose of workers and + # `pin_memory_thread` is to serve the loader process. If + # loader process is already exiting, we don't really care if + # the queues are corrupted. + # + # + # Now let's get back to 1: + # how we gracefully exit the workers when the last reference to the + # iterator is gone. + # + # To achieve this, we implement the following logic along with the design + # choices mentioned above: + # + # `workers_done_event`: + # A `multiprocessing.Event` shared among the main process and all worker + # processes. This is used to signal the workers that the iterator is + # shutting down. After it is set, they will not send processed data to + # queues anymore, and only wait for the final `None` before exiting. + # `done_event` isn't strictly needed. I.e., we can just check for `None` + # from the input queue, but it allows us to skip wasting resources + # processing data if we are already shutting down. + # + # `pin_memory_thread_done_event`: + # A `threading.Event` for a similar purpose to that of + # `workers_done_event`, but is for the `pin_memory_thread`. The reason + # that separate events are needed is that `pin_memory_thread` reads from + # the output queue of the workers. But the workers, upon seeing that + # `workers_done_event` is set, only wants to see the final `None`, and is + # not required to flush all data in the output queue (e.g., it may call + # `cancel_join_thread` on that queue if its `IterableDataset` iterator + # happens to exhaust coincidentally, which is out of the control of the + # main process). Thus, since we will exit `pin_memory_thread` before the + # workers (see below), two separate events are used. + # + # NOTE: In short, the protocol is that the main process will set these + # `done_event`s and then the corresponding processes/threads a `None`, + # and that they may exit at any time after receiving the `None`. + # + # NOTE: Using `None` as the final signal is valid, since normal data will + # always be a 2-tuple with the 1st element being the index of the data + # transferred (different from dataset index/key), and the 2nd being + # either the dataset key or the data sample (depending on which part + # of the data model the queue is at). + # + # [ worker processes ] + # While loader process is alive: + # Get from `index_queue`. + # If get anything else, + # Check `workers_done_event`. + # If set, continue to next iteration + # i.e., keep getting until see the `None`, then exit. + # Otherwise, process data: + # If is fetching from an `IterableDataset` and the iterator + # is exhausted, send an `_IterableDatasetStopIteration` + # object to signal iteration end. The main process, upon + # receiving such an object, will send `None` to this + # worker and not use the corresponding `index_queue` + # anymore. + # If timed out, + # No matter `workers_done_event` is set (still need to see `None`) + # or not, must continue to next iteration. + # (outside loop) + # If `workers_done_event` is set, (this can be False with `IterableDataset`) + # `data_queue.cancel_join_thread()`. (Everything is ending here: + # main process won't read from it; + # other workers will also call + # `cancel_join_thread`.) + # + # [ pin_memory_thread ] + # # No need to check main thread. If this thread is alive, the main loader + # # thread must be alive, because this thread is set as daemonic. + # While `pin_memory_thread_done_event` is not set: + # Get from `worker_result_queue`. + # If timed out, continue to get in the next iteration. + # Otherwise, process data. + # While `pin_memory_thread_done_event` is not set: + # Put processed data to `data_queue` (a `queue.Queue` with blocking put) + # If timed out, continue to put in the next iteration. + # Otherwise, break, i.e., continuing to the out loop. + # + # NOTE: we don't check the status of the main thread because + # 1. if the process is killed by fatal signal, `pin_memory_thread` + # ends. + # 2. in other cases, either the cleaning-up in __del__ or the + # automatic exit of daemonic thread will take care of it. + # This won't busy-wait either because `.get(timeout)` does not + # busy-wait. + # + # [ main process ] + # In the DataLoader Iter's `__del__` + # b.
